First, round the uncertainty to two significant figures, that is, 2.0 mg. (Notice that two significant figures are shown. The zero is a significant figure since it follows a non zero number.) Then, round the correction to the same number of decimal places as the uncertainty statement, that is, 4.3 mg. Report the correction as 4.3 mg ± 2.0 mg.

Section 1.3.2: Significant Digits after Adding or Subtracting When you add or subtract measurements, then you have to round your answer to the precision of the least accurate measurement. That’s because the uncertainty in the least precise measurement overwhelms the precision of the other measurements.

Round down whenever the digit following the last significant figure is a 0,1,2,3, or 4. For example, 30.24 becomes 30.2. Round up whenever the digit following the last significant figure is a 6,7,8,9 or a 5 with any nonzero digit at any place after it. For example, 22.49 becomes 22.5.

When multiplying and dividing, all you do is see which number has the fewest significant digits, and then round your answer to that same number of digits. In this problem = 183.5534. The 0.095 in the denominator has only two significant digits, and that limits your answer to two significant digits: 180. Mixed operations

0.00035 has two significant digits (only the 3 and 5 tell us something; the other zeroes are placeholders, only providing information about relative size) 0.000350 has three significant digits (that last zero tells us that the measurement was made accurate to that last digit, which just happened to have a value of zero)
